Assertion (A): | When PCl5 is heated then PCl3 and Cl2 are obtained as products. |
Reason (R): | PCl5 gives POCl3 with water. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | (A) is false but (R) is true. |
Consider the following reaction:
PCl5 + H2O → A + 2HCl
The product A is :
1. H3PO2
2. H3PO4
3. POCl3
4. None of the above
Consider the following reactions,
a. C2H4 + 3O2→ X + 2H2O
b. 4Al+ 3O2 → Z
X and Z are respectively-
1. X = 1 mole of CO2; Z = 4 moles of Al2O3
2. X = 2 moles of ethanoic acid; Z = 2 moles of AlO3
3. X = 2 moles of CO2; Z = 2 moles of Al2O3
4. X = 2 moles of ethanoic acid; Z = 4 moles of Al2O3
